Nerve and Muscle Stimulator
S88 DUAL OUTPUT SQUARE PULSE STIMULATOR

Single, Repetitive and Train Outputs. TTL Synchronization, External Analog Control of Rate

The S88 is a dual output, general purpose stimulator for nerve and muscle stimulation procedures. Applications extend from single cell to entire muscle stimulation. The two output channels can be operated independently or synchronized to produce complex paradigms. The outputs are nonisolated constant voltage positive pulses.

Features include computer compatibility and flexibility of synchronization circuits. The synchronous inputs and outputs are TTL, 5 volt, PC compatible. A rear DB25S connector permits external analog control of the timing circuits.

Optional Stimulus Isolation Units are available for applications requiring isolation and/or constant current.
